摘要:
A magenta toner, a yellow toner, a cyan toner, and a black toner each for development of an electrostatic latent image ad a combination of the four color toners for obtaining a full color image are disclosed, the magenta toner containing a naphthol type organic pigment represented by formula (I): ##STR1## the yellow toner containing a disazo type organic pigment represented by formula (II): ##STR2## the cyan toner containing a .beta. type copper phthalocyanine pigment and a polychlorocopper phthalocyanine pigment, and the black toner containing at least one of an isoindolinone type yellow pigment and a tetrachloroisoindolinone type yellow pigment, at least one of a quinacridone type red pigment and a perylene type red pigment, and a phthalocyanine type blue pigment. The color toners are unaffected by environmental changes and capable of providing color images having stable characteristics.

摘要:
An interchangeable lens assembly for a camera having a first and a second assembly unit releasably coupled to each other. The first assembly unit being directly coupleable to the camera and including an adapter member and a lens barrel which are relatively rotatable. The adapter member includes a retainer device for maintaining the adapter member rotatively fixed when the first assembly unit is mounted on the camera and a first coupling member adapted to engage a first complementary coupling member in the camera to enable releasable coupling and decoupling of the first unit with the camera. A mechanism is provided for returning the aperture signal transmission member to a predetermined position relative to the adapter member when the first assembly unit is dismounted from the camera. The lens assembly also includes a first interlocking mechanism for locking the adapter member and the lens barrel in a predetermined rotative position relative to each other when the first assembly unit is dismounted from the camera, a second locking mechanism for maintaining the adapter member and the lens barrel rotatively fixed relative to each other at a second angular position when the first assembly unit is mounted on the camera and a third locking mechanism for releasably locking the first and second lens units together when they are operatively coupled.
摘要:
Method of treating a sticky material-containing exhaust gas to remove the sticky material therefrom, by introducing pulverized coal or coke having a particle size of 0.3mm or less into the bottom of a hopper, which is positioned below, and integrally connected with, a bag-house containing bag-filters, to form a protective layer of pulverized coal or coke having a thickness of at least 1mm on the surface of each bag-filter, and then introducing the sticky material-containing exhaust gas into said hopper in a manner such that the gas passes through said protective layer while said protective layer captures and retains the sticky material.
